Halaye na nitrile roba da EPDM roba da ingancin roba tiyo

1. Nitrile roba
Nitrile robar ana amfani da shi musamman wajen kera kayayyakin roba masu jure wa mai.NBR a takaice, roba roba da aka yi ta hanyar copolymerizing butadiene da acrylonitrile.Robar roba ce mai kyau mai juriya (musamman man alkane) da juriyar tsufa.
Nitrile roba yana samuwa ta hanyar emulsion polymerization na butadiene da acrylonitrile.Nitrile roba ne yafi samar da low-zazzabi emulsion polymerization.Yana da kyakkyawan juriya na mai, juriya mai girma, juriya mai kyau da ƙarfi da ƙarfi..
Lalacewarsa shine rashin juriya mara ƙarancin zafin jiki, ƙarancin juriya na ozone, ƙarancin aikin rufewa, da ƙarancin ƙarfi kaɗan.Ana iya amfani da shi na dogon lokaci a cikin iska a 120 ° C ko a cikin mai a 150 ° C.
Bugu da kari, shi ma yana da kyakykyawan juriya na ruwa, tsantsar iska da kyakkyawan aikin haɗin gwiwa, kuma ana amfani da shi sosai wajen kera samfuran roba iri-iri masu jure wa mai.

2. EPDM roba
EPDM roba ba iyakacin duniya, cikakken tsari.Abin da ake kira "mara iyaka" yana nufin cewa kwayoyin da suka hada da polymer ba su ƙunshi ƙungiyoyin polar ba.Abin da ake kira "jikewa" yana nufin cewa kwayoyin da suka hada da polymer ba su ƙunshi nau'i biyu ba.
EPDM (etylene propylene diene monomer), a matsayin nau'in roba mai kyau mai kyau, juriya na juriya, juriya na zafi, juriya na yanayi, juriya na ozone, ruwa mai dadi da juriya na ruwa, an yi amfani dashi sosai a cikin kayan roba don motoci.
